Abstract :
A novel retrodirective transponder is introduced, with potential application in high performance digital communications. Active circuitry is integrated for phase conjugation, giving conversion gain in addition to phase conjugating operation, therefore enabling retrodirectivity. Applying a modulated LO signal, the array can send local information directly back to the base station on demand.
